Struct sc_rpc_server::middleware::Middleware

pub struct Middleware<S> { /* private fields */ }

JSON-RPC middleware that handles metrics and rate-limiting.

These are part of the same middleware because the metrics needs to know whether a call was rate-limited or not because it will impact the roundtrip for a call.

Trait Implementations

impl<'a, S> RpcServiceT<'a> for Middleware<S>

where S: Send + Sync + RpcServiceT<'a> + Clone + 'static,

type Future = Pin<Box<dyn Future<Output = MethodResponse> + Send + 'a>>

The future response value.

fn call(&self, req: Request<'a>) -> Self::Future

Process a single JSON-RPC call it may be a subscription or regular call. In this interface they are treated in the same way but it’s possible to distinguish those based on the MethodResponse.
